Scribing panel lines ? (Swanny or others)

Swanny, I just read the demo for scribing panel lines on your site and have a question, do you scribe right over the raised line or beside it? Also I assume this would work just as well to add non existant detail.

I scribed right over the existing line. Whatever did not come off with the scribe was removed by the followup sanding.

Thanks, that was one part I wasn’t sure about. Really nice demos you did, I will be using a few of them to hopefully fix the Guardian.
